A Last Will and Testament — commonly called a “will” — is one of the most foundational estate planning documents a person can create.
At its core, a will is a legal instruction manual.
It tells the probate court:
- Who should receive your assets
- Who should manage your estate
- Who should raise your minor children
- How debts and taxes should be handled
While wills are widely known, many families misunderstand what they do — and just as importantly, what they do not do.
This guide explains how wills function, how they are used, and how they fit into a broader estate plan.
What A Will Actually Does
A will becomes legally operative only after death.
Once admitted to probate, it directs the court and executor on how to administer the estate.
Key functions include asset distribution, fiduciary appointment, and guardianship designation.
Naming Beneficiaries
One of the most recognized functions of a will is naming who inherits your property.
You can leave assets to:
- Spouses
- Children
- Extended family
- Friends
- Charities
You can also designate percentages, specific gifts, or contingent beneficiaries.
Without a will, Missouri intestacy statutes determine inheritance — regardless of your personal wishes.
If you want to understand how intestacy works, review what happens when someone dies without an estate plan in Missouri.
Appointing An Executor
A will allows you to nominate an executor (Personal Representative) to administer your estate.
This person is responsible for:
- Opening probate
- Collecting assets
- Paying debts
- Distributing inheritances
Choosing a responsible executor is critical because they carry fiduciary duties and legal liability.
If you want to understand the role more deeply, review what executors must do when settling an estate.
Naming Guardians For Minor Children
For parents, this is often the most important function of a will.
A will allows you to nominate guardians to raise your children if both parents pass.
Without this nomination, courts decide guardianship — often after family disputes or hearings.
Parents should carefully evaluate guardian choices and backup options.
If you have children, it’s also important to understand why parents often create trusts alongside wills.
Directing How Assets Are Distributed
Wills allow for detailed distribution instructions, including:
- Age-based distributions
- Staggered inheritances
- Specific item gifts
- Charitable bequests
However, minor children cannot inherit assets outright.
If children are beneficiaries, courts may require conservatorship unless trust planning is included.
What A Will Does NOT Do
A will is powerful — but limited.
Many people mistakenly believe a will avoids probate.
It does not.
A will directs probate — it does not bypass it.
Assets passing under a will must still go through court administration before distribution.
If probate avoidance is a goal, review how families avoid probate using trusts and beneficiary planning.
Not Sure Whether A Will Alone Is Enough?
Many families create wills but overlook probate exposure, trust planning, or guardianship structuring.
TrustFully helps Missouri families create estate plans that go beyond basic wills — incorporating trusts, probate avoidance, and long-term protection.

How A Will Is Used After Death
After death, the will is filed with the probate court.
The court then:
- Validates the will
- Appoints the executor
- Oversees administration
- Authorizes distributions
This process ensures debts are paid and beneficiaries receive inheritances properly.
When A Will Is Enough — And When It Isn’t
A will alone may be sufficient when:
- Estate value is modest
- Probate exposure is acceptable
- No minor trust planning is needed
However, more comprehensive planning may be needed when:
- Minor children are involved
- Probate avoidance is desired
- Asset protection is needed
- Privacy is important
Wills vs. Trusts
Wills and trusts serve different roles.
A will directs probate distribution.
A trust can bypass probate entirely.
Many estate plans use both in tandem.
To understand the distinction, review how wills and trusts function together within estate plans.
Final Thoughts
A will is one of the most important legal documents you can create.
It ensures your wishes are followed, your family is protected, and your estate is administered according to your instructions.
But while wills are foundational, they are often just one component of a comprehensive estate plan.
